Feartan:

HEDP a tha na neach-dìon corrach organophosphoric acid. Faodaidh e chelate le ions Fe, Cu, agus Zn gus todhar chelating seasmhach a chruthachadh. Faodaidh e na stuthan oxidized a sgaoileadh air uachdar nam meatailtean sin. HEDP a’ sealltainn sgèile sàr-mhath agus buaidhean casg meirg fo teòthachd 250 ℃. HEDP tha seasmhachd ceimigeach math aige fo luach pH àrd, duilich a bhith air a uisgeachadh, agus duilich a bhith air a lobhadh fo chumhachan solais is teas àbhaisteach. Tha a fhulangas searbhag / alcalan agus clorine oxidation nas fheàrr na fulangas searbhagan organophosphoric eile (salann). HEDP can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore, HEDP has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects.

An staid chruaidh a HEDP is crystal powder, suitable for usage in winter and freezing districts. Because of its high purity, it can be used as cleaning agent in electronic fields and as additives in daily chemicals.

Cleachdadh:

HEDP is used as scale and corrosion inhibition in circulating cool water system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.. In light woven industry, HEDP is used as detergent for metal and nonmetal. In dyeing industry, HEDP is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating, HEDP is used as chelating agent. The dosage of 1-10mg/L is preferred as scale inhibitor, 10-50mg/L as corrosion inhibitor, and 1000-2000mg/L as detergent. Usually, HEDP is used together with polycarboxylic acid.

Pacadh agus stòradh:

HEDP liquid: 200L plastic drum,IBC(1000L),customers’ requirement.

HEDP solid: 25kg/bag,customers’ requirement.

Stòradh airson dusan mìos ann an seòmar dubharach agus àite tioram.

Sàbhailteachd agus dìon:

Tha HEDP searbhagach. Thoir aire do dhìon saothair rè obrachadh. Seachain conaltradh le craiceann agus sùilean. Ma tha e a 'frasadh air a' bhodhaig, nigh sa bhad le uisge gu leòr.
